Aspheric Cylindrical Lens
Unlike spherical lenses, cylindrical lenses concentrate the incident light not at the focal point but along the focal line, and they are mainly used to change the imaging size in high-precision testing instruments and devices such as the cavity plate of high-power laser resonator and long-distance line interferometer.
Ordinary cylindrical lens can be manufactured using traditional polishing methods. But aspherical cylindrical lens need to use a multi-axis single-point diamond lathe for ultra-precision turning, and the finished product is very difficult.
China Star Optics can provide customized high precision aspheric lenses and aspheric cylindrical lenses for laser and precision optical applications according to customer requirements. Aspheric products with diameters from φ5 to φ200mm, surface quality better than 20/10 and surface irregularity better than λ/4 are available on request.
China Star Optics offers high quality custom designed aspheric lens in any quantity from testing sample to mass production. Extremely small MOQ helps to reduce your initial project investment.
